CLAMPING DEVICE FOR CGMBINATION STORM AND SCREEN DOOB$.

To all whom it may concern.

Be it known that I, HAROLD L. Bnimni'u', a citizen of the United States,residing at llluscatine, in the county of Muscatine and State of Iowa,have invented certain new and useful Improvements in Clamping Devicesfor Combination Storm and Screen Doors; and I hereby declare that thefollowing is a full, clear, and exact. description thereof, referencebeing had to the accompanying drawings, which form part of thisspecification.

This invention is a novel clamping device particularly designed for usein so called combination storm and screen doors which are provided withremovable interchangeable panels, usually a glazed panel to be used incold weather and a screen panel to be used in warm weather; thus makingthe door convertible and usable either as a stormdoor or a screen door.

The ob ect of the inventionis to provide a very simple and etliclentclamping means readilyapplicable to the door frame whereby the removablepanel can be quietly and firmly clamped in position or readily removed,thus permitting the glazed panel to be substituted for the screen panel,or vice versa, without the aid of a skilled mechanic.

, in the accon'ipanying drawings I have illustrated some practicalembodiments of the invention and will describe the same with referencethereto, andthe claims sum- HIENlZO the essentialsof the invention andnovel features of construction and combinations of parts for whichprotection is desired. i

l. have shown only part of the door and part of the panel, these beingof wellv known. construction it is not necessary to show the entire dooror panel.

In the drawings Figure 1V is a perspective view of one of the novelclamping devices used to fasten a removable panel in a door.

Figure 2 is a sectional view on the line vice.

Application filed April 30, 1925. Serial No. 27,011.

Figure 1- is a perspective view of the se eral parts of the clampingdevice shown in Figures 1 to 3, detached.

Figure 5 is a similar view of a slightly size or shape for a glazedorscreelrpanel of suitable size and shape. A partof the door around thepanel opening is shown at 1 in the drawing, and said. opening is adapted to be closed by a suitable panel a part of which is shown at 2 in thedrawings. The portion 1 of the door is provided with a flange 1projecting into the panel opening at one side thereof, and against theinner face of this one face of the panel 2 abuts, the flange 1overlapping the adjacent face of the panel 2. Said panel 2 is providedwith a flange 2 on its outer edge which overlaps the adjacent face ofthe door 1 epposite the flange 1",as shown in Figure fz.

-Preferably the panel 2 has a groove 2" in its outer edge adjacent theflange 2, the side of slots 1 in which are placed clamping members 3which are preferably .clisl slmped and preferably made of stainpedmetal. but maybe cast. I These clamping members have their outerperipheries preferably beveled as at 3" to engage the beveled side ofthe groove 2 to receive the pane] in position in the door. 1

The disk 3 as shown in F 1 to l; has an angular recess 3 in its facelocated eccentrically thereof and this recess is engaged by the innercorrespondingly shaped end 4" of a rotatable stud 1, which is neatlylitted. in a bore 1 extending through one side of the door 1 intotheslot 1 and adjacent the flange 1 The outer end of the stud 4. may beprovided with a slot, or socket, or otherwise ill-U shaped, to enable itto be rotated by an actuating implement, such as a screw driver orwrench.

The slot 1 is deep enough to practically admit the entire membertherein, as indicated in dotted lines in Figure 3, but preterably theslot is so narrow that axial movement of the member 3 in the slot isprevented. The member 3 can thus be confined in the slot by the looseengagement of the angular head 4f of the stud l with the recess 3 andwhen so ei'igaged the disk can not fall out of the slot, but it may berotated orbit-ally by turning the stud l.

Preferably stud 4t is surrounded by a sleeve 5 which is pressed intosaid bore and terms a bearing for the stud and prevents it wearing thewood of the door. The stud *It can not be drawn outward through thebushing because the inner end or head 4; of the stud is slightly largerin diameter than the bushing as shown.

The outer end of the stud preferably comes flush with the outer end ofthe bush- 0 ing 5, which is preferably fiuslt with the suri ace of thedoor;

By turning the stud lthe disk 3 can be turned to the position indicatedin dotted lines in. 3, in which position it will be wholly within thesocket or slot 1", and hence disengaged from the groove 2" and when theclamping inembersare in such position the panel 2 can be-readily removedtrom or replaced in the door. lVhen the panel is properly placed in thedoor the disk can be rotated into engagement with the groove 2*, byproperly turning the stud i-, and thebe'veled edge 3" of the disk 3 willengage the bevelled "side the groove 2 and clamp the panel 2 "tightlyagainst the flange ll of the QllOOlf, the flat side of the disk 3bearing against the side wall of the slot l opposite the bore 1.

In the modification shown in Figure 5 the construction is practicallythe same as that shown in Figure 4, except that the disk 3 is providedwith a non-circular slot 3, and the stuthl is provided on its inner endwith a correspondingly shaped. head 4: adapted to engage slot 3 so astocause the disk -to turn with the stud in the manner above described.

In the modification shown in Figure 6 the disk 3 has-a rectangularopening or .re cess 3 and the stud l has a correspondin ly shaped. headl on its inner "end to engage this recess.

ln each construction the parts operate exactly alike, but for-simplicityand economy I at present consider the form shown in Figures 1-to 'lpreterable.

In assembling the device the disk 3 is inserted in the slot 1 with itsopening or socket registering, with thebore l,-then stud -lis enteredInto-1301 6 "1. Until the inner end of the stud 1S properly engaged withcan be turned with the stud, and operated as shown and described.

I claim:

1. Bleans for securing a panel having a groove in its edge, in a doorhaving a slot adapted to register with the groove in the panel when thelatter is in place ;:said means comprising a beveled edge member adapt'ed to be inserted in. the slot and in one position to have its bevelededge engage the groove in the panel and clamp the latter in position; arotatable stud extendii'ig into the slot and detachably engaging thedisk, and whereby the latter is retained in place in the slot and alsomay be rotated to cause its beveled portion to engage or disengage thegroove in the panel; and means to retain the stud in place.

2. In combination with a door having an opening and a slot at the edgeof the opening; and a removable panel having a groove in its edgeadapted to register with the slot in the door when the panel is inplace; of a rotatable disk like member in said slot having aneccentrically located 515 and a beveled adapted in one pos engage thegroove in the panel and bind the same in place in the door, and inanother position to permit the panel to be removed, with a rotatablestud projecting into the slot and having its inner end engaged with therecess in the disk; said dish being held against axial movement by thewalls of the slot and being retained. in the slot by its engagement withsaid stud.

3. Means for securing a door panel having a groove in its edge, in anopening in a door, said door having a slot at the edge of the openingadapted to register with the groove in the panel when the latter is inplace; said means comprising a. circular disk having a beveled edge andad; cd to be inserted in said slot adapted in one position to engage thegroztr-ue in the panel and bind the panel in the frame, and in anotherposition to permit the panel to be removed; said disk also having aneccentrically located recess; a rotatable stud mounted in the door andprojecting into the slot and having its inner end loose y engaged in therecess in the disk; said disk being held against axial movement by thewalls of the slot and being retained in the slot by its engagement withsaid stud; and, a bushing for holding the stud in place.

-l-. A clamping device for the purpose specified, comprising a disk likemember having an cccentrically located recess or slot; a rotatable studhaving its end dctachably enga ed with the recess in the d whereby thelatter is retained in place, and

may also be rotated; and a bushing for said stud whereby it may beretained in place.

5.
